The Impact

The paper reports the results of the strengthening simulation process. A new kinematics of deforming rollers ensuring a surface plastic deformation of shafts of low rigidity was considered. On the basis of the theory of low elasto-plastic deforma-tions and a method of finite elements there were formed simulators of a strengthening process allowing the definition of a stressed state in a sample depending on the form and kinematics of an indenter. With the aid of ANSYSWB software there was considered the impact of some circuits of deformation upon a stressed state: running-in by rolling, running-in by slip, running-in by one and two rollers with the rotation with regard to a diametrical axis. On the basis of simulation results it was revealed that the basic factors affecting a stress-strain state of parts are geometry, a form, a mutual location of elements of a tool deformed and their kinematics with regard to a part worked.

Surface Layer Quality

There are offered dependences for the definition of parameters formed for surface layer quality when finishing and finish-strengthening with surface-plastic deformation, for the definition of processing modes, tool geometrical parameters taking into account initial parameters of surface layer quality. Criteria for the choice of the processing method ensuring quality parameters required for a surface layer and surface operation properties are offered.

Scientific Value

Obtaining of the quality of the inner surface of the hydraulic cylinders and its optimization is an urgent problem in the enterprise. The article presents the results of a study to improve the finishing process of deep holes in thin-walled sleeves. The authors used the combination of the cutting process and surface plastic deformation for improving metal processing. The selected main parameters for ensuring the quality of the surface are roughness index and the value of internal stresses in the surface layer of hydraulic cylinders. To determine the hardening depth of the inner surface of the deep hole of the liner, the oblique thin section method was used. A mathematical model of the combined processing was obtained. The research results make it possible to recommend combined hole processing that combines cutting and plastic deformation. The results obtained in this work will improve the processing of deep holes of hydraulic cylinders, and the developed mathematical model has practical and theoretical scientific value.
